Would be a possibility, but I've set my MCP altitude on 0 so that the aircraft can descent. And I picked all the info from the CDU regarding airport and runway. If that is not enough, which altitude do I have to change and where do I get the precise information from?

 

On final (to put it simpel), you should set your altitude to the Missed Approach altitude.

I cannot see any situation where you set the altitude to 0 on the MCP....

I love flying the NGX, but have now had a few times that with the AP approach option the plane comes flying in too high (few hundred feet), which makes me have to abort the landing and do a go-around. The funny bit is that with the PMDG 747 it works perfectly.

 

Apparently I'm doing something wrong, although I am sure I set the altimeter correctly, and I use the airport data from the CDU. Anyone have a guess what the problem could be?

 

You're probably not actually in the VOR LOC | G/S modes. If it says LNAV | VNAV PTH or FAC | G/P (or LNAV/VOR | G/P etc) those are the Integrated Approach Navigation modes - you cannot do an autoland in anything other than the full ILS modes with both autopilots connected. (LOC | G/S).

Thanks for all the replies. Surely I don't set the MCP to 0 really, but it was just to show that at least I put it to a lower altitude other than cruising altitude so that the plane can do a normal descent. Anyway, the reply from tabs is the answer I was looking for I guess. And indeed, I just did another flight from London to Amsterdam and had the same problem with FAC | G/P activated. Now I can pinpoint that problem and find how to get a full LOC | G/S.

Thanks again :)

Are your altimeter pressure settings, (QNH), correct?

Ok, found the problem, it was I ;) I did not set the ILS frequencies and the runway height and length during descent. Anyway I fixed it and it is now working like a charm :)
